INGREDIENTS GUIDE · UPDATED OCTOBER 2026
What is in a nicotine-free vape? The short answer is
that many conventional 0mg e-liquids use a carrier base
such as propylene glycol (PG), vegetable glycerin (VG),
flavoring ingredients and sometimes other additives.
The exact formula varies by manufacturer and product,
especially for vitamin-labeled and botanical formats.
QUICK ANSWER
Nicotine-free describes the nicotine level,
not the entire ingredient list.
A product labeled 0mg or zero nicotine may still contain
carrier liquids, flavoring compounds and other ingredients.
There is no single universal recipe for every nicotine-free
vape, so the individual label and manufacturer disclosure
remain more important than assuming every 0mg product uses
the same formula.
If your question is about where a nicotine-free vape can be used rather than what it contains, see Can You Vape Indoors? Rules for Nicotine-Free Vapes.
If you are researching purchase restrictions rather than ingredients, see our guide to age rules for buying nicotine-free vapes.
If you are wondering how aerosol interacts with building detection systems, see Do Vapes Set Off Smoke Alarms?
E-liquid also has to reach the wick correctly during use. For related device-use troubleshooting, see our wick and liquid-delivery guide.
E-liquid composition can also change during long-term storage. See our e-liquid storage and aging guide.
What Is Usually in a Nicotine-Free Vape?
Conventional e-liquids commonly use propylene glycol,
vegetable glycerin and flavoring ingredients as part of
the liquid that is heated into an aerosol. The U.S. Food
and Drug Administration describes e-liquids as commonly
containing flavorings, propylene glycol, vegetable glycerin
and other ingredients.
Removing nicotine changes one important part of that formula,
but it does not automatically remove the carrier liquids,
flavor compounds or every other additive. Formulas can also
differ substantially between brands and product categories.
| Ingredient group | Typical role | Always present? |
|---|---|---|
| Propylene glycol (PG) |
Common liquid carrier used in many e-liquid formulas. |
No. Formula ratios and ingredients vary. |
| Vegetable glycerin (VG) |
Common carrier that contributes to aerosol formation. |
No universal ratio applies to every product. |
| Flavoring ingredients |
Create mint, fruit, dessert and other flavor profiles. |
Common, but the specific compounds vary. |
| Cooling or sweetening ingredients | May modify sweetness or cooling sensation. | Product-dependent. |
| Nicotine |
Nicotine ingredient found in many conventional vape products. |
A genuine 0mg / nicotine-free product is intended to be labeled without nicotine. |
| Other active or botanical ingredients | May appear in specialty product categories. |
Only when specifically disclosed for that product. |
What Do PG and VG Do?
Propylene glycol (PG)
PG is one of the carrier liquids commonly used in e-liquids.
It can help distribute flavoring ingredients throughout the
liquid. The amount used is not standardized across every
nicotine-free product.
Vegetable glycerin (VG)
VG is another common carrier. Its physical properties differ
from PG, and manufacturers may use different PG/VG proportions
depending on the formula and device.
A label that says “nicotine-free” tells you about nicotine.
It does not, by itself, tell you the PG/VG ratio or identify
every flavoring compound.
What Does 0mg Nicotine Mean?
“0mg,” “0mg/mL,” “zero nicotine” and “nicotine-free” are
commonly used to indicate that a product is labeled without
nicotine. They do not mean that the device contains only
water or that the aerosol contains no other substances.
Important distinction:
the CDC notes that e-cigarette aerosol is not harmless
“water vapor.” It can contain particles and other substances,
and some products marketed as containing zero percent nicotine
have previously been found to contain nicotine. For that reason,
labeling and source transparency matter even when shopping for
0mg products.
Nicotine-Free Does Not Mean Ingredient-Free
One of the easiest misunderstandings is to treat “no nicotine”
as though it means “nothing else in the liquid.” Those are two
different questions.
Nicotine status answers:
Is this product labeled with nicotine?
Ingredient disclosure answers:
What else is in this specific formula?
That distinction becomes especially important when comparing
standard nicotine-free products with vitamin-labeled or
botanical formats.
Standard, Vitamin-Labeled and Botanical Formulas
Standard Nicotine-Free
Usually positioned around flavor and nicotine status.
Check the individual product label for its actual
carrier and flavoring disclosure.
Vitamin-Labeled
May identify an additional vitamin-related ingredient
or product concept. The word “vitamin” does not make
an inhaled product equivalent to a dietary supplement.
Botanical
May identify plant-derived or plant-labeled ingredients.
Botanical terminology alone does not establish safety,
effectiveness or a medical benefit.
You can compare these categories separately on our
Nicotine-Free Vapes,
Vitamin Vapes
and
Botanical Diffusers
pages.
How to Read a Nicotine-Free Vape Label
Instead of relying only on the front-of-package marketing
phrase, check several pieces of information together.
Look for an explicit 0mg, 0% or nicotine-free
statement rather than assuming from branding.
Check whether the manufacturer identifies carrier
liquids, flavoring or category-specific ingredients.
Distinguish standard nicotine-free, vitamin-labeled
and botanical formats instead of treating them as
identical formulas.
Review device format, inhale count and other
specifications separately from ingredient claims.
Ingredient presence is not proof of medical,
nutritional or therapeutic effectiveness.
Formulas and product versions can change, so check
the current product information before purchasing.
What Is Actually in HealthyVape Products?
HealthyVape currently organizes its range into standard
nicotine-free, vitamin-labeled and botanical formats.
Because these categories are not necessarily identical
formulas, this guide does not claim that every HealthyVape
device contains the same PG/VG ratio, flavoring system or
active ingredients.
The correct approach is to use the individual product page
and label for the product-specific disclosure, while this
guide explains the ingredient categories shoppers commonly
encounter.
Is Nicotine-Free Vape Aerosol Just Water Vapor?
No. A vape device heats a liquid to create an aerosol.
The CDC specifically distinguishes e-cigarette aerosol from
harmless water vapor. The aerosol can contain small particles
and substances produced from or carried by the liquid and
device.
This is also why an ingredient being suitable for use in food
does not automatically establish that inhaling the same
ingredient is harmless. Eating and inhaling are different
exposure routes.

Nicotine-Free Vape Ingredients FAQ
What is in a nicotine-free vape?
Many conventional nicotine-free e-liquids contain
carrier liquids such as propylene glycol (PG) and
vegetable glycerin (VG), plus flavoring ingredients
and sometimes other additives. Exact formulas vary
by product and manufacturer.
Do nicotine-free vapes contain PG and VG?
PG and VG are common e-liquid carriers, but you should
not assume that every nicotine-free product uses the
same ingredients or ratio. Check the specific product
disclosure.
Does 0mg mean there are no chemicals in the vape?
No. 0mg refers to nicotine concentration. Other
ingredients can still be present, including carrier
liquids and flavoring compounds.
Is nicotine-free vape aerosol just water vapor?
No. Vape devices create an aerosol by heating liquid.
Public-health agencies distinguish that aerosol from
harmless water vapor.
Are vitamin and botanical vapes made from the same formula?
Not necessarily. Vitamin-labeled and botanical products
can include category-specific ingredients, so their
product labels should be reviewed separately rather than
assuming one universal nicotine-free formula.
